My wife hasn't showered since like Sunday, she's been too sick to get out of bed for the most part. I don't think she noticed my lack of hygiene. She's improving though, she could come home as early as this evening.

The LED light I used to test with is basically on when the relay is off, though it flickers. It's about exactly the same as it was with the relay board before we added the 1.5k resister.

When you say increase load current do you mean just attach something larger to the load on the relay? With pneumatic solenoids and my coolant pump I'm not sure that's an option, not unless I add a incandescent light bulb in there or something.
